摘要 針對現有游艇模擬器中無法模擬游艇靜水“海豚運動”的問題,基于游艇高速航行受力本質進行分析,結合平板滑行理論和Savitsky關于棱柱形滑行艇的相關研究,對游艇幾何模型進行合理簡化,求解游艇靜水中滑行運動姿態.基于高頻自由面假設和切片理論計算游艇垂蕩、縱搖水動力系數,采用Routh-Hurwitz線性穩定性判據尋找游艇發生“海豚運動”閾值.提出引入人工干預的方法激勵處于不穩定運動狀態的游艇,使其發生“海豚運動”并進行數值仿真試驗.試驗結果表明當且僅當游艇處于不穩定運動狀態時人工干預可以誘導游艇進行“海豚運動”,數值仿真結果與模型試驗結果符合良好.將算法與游艇模擬器相結合進行工程應用試驗,游艇模擬器運行穩定、效果良好,實現了游艇模擬器中游艇“海豚運動”的仿真.

Abstract Porpoising motion is still a unsolved problem in yacht simulator.By combining the flat sliding theory and related work on prismatic planing craft of Savitsky,force of yacht was analysed.Yacht geometric model was reasonably simplified,and the yacht's motion posture was solved.Hydrodynamic coefficients were calculated by high frequency free surface assumption and strip theory.Porpoising motion threshold of yacht was found by Routh-Hurwitz stability criterion.The method of artificial intervention was proposed to promote the yacht into porpoising condition,and numerical experiments were made.The numerical results agree well with the model test results.The algorithm was embedded in the yacht simulator for engineering application.The yacht simulator runs stably with good results.The porpoising motion simulation in yacht simulator is implemented.
Keywords yacht simulator ; mathematical model of movement ; porpoising motion ; stability analysis ; artificial intervention
